JP-A-6-6772

  In the program information, the broadcast time information indicating the broadcast time of the program is represented by a broadcast start time and a broadcast end time. When a recording reservation is set using broadcast time information, a program that started broadcasting before the broadcast start time of the program reserved for recording (hereinafter referred to as `` recording reserved program '') will also be Regardless, it may be extended and broadcast. Such a situation often occurs in sports broadcast programs, for example.

  In this way, a program that has started broadcasting before a program reserved for recording (hereinafter referred to as a “pre-broadcast program”) is broadcast with its broadcast time extended beyond its end time, Broadcast start of the scheduled recording program is delayed by the extended broadcasting time. That is, the broadcast time zone of the scheduled recording broadcast is shifted by the extension time of the preceding program with respect to the scheduled recording program.

  However, in the recording apparatus as described above, the reserved recording start time and reserved end time of the scheduled recording program are not updated according to the extension of the preceding program. As a result, when the preceding program is extended like an extension of a sports broadcast, there is a problem that the scheduled recording program is not recorded for the extended time.

  In the present invention, when there is a possibility that a program broadcast prior to the scheduled recording program is extended and broadcast beyond the original broadcast end time, the program of the scheduled recording program is determined at the discretion of the user. It is an object of the present invention to provide a reservation recording control apparatus that can make a recording reservation by extending the recording end time by a predetermined time.

This onset bright, each broadcast source a plurality of programs to be broadcast, broadcast start time, broadcast end time, and the program information including information indicating the genre to receive a broadcast signal multiplexed, based on the program information Te, a reserved recording controller for reserved recording two or more specific program among the plurality of programs in the recording apparatus,
The recording apparatus selects a broadcast source for broadcasting the first specific program among the specific programs to be recorded for reservation, and receives a broadcast signal to make a reservation recording start time and a reserved recording end time for the first specific program. And a reservation recording controller capable of delaying the time for ending reservation recording of the first specific program by a desired time ,
When the selected broadcast source broadcasts a program in which the broadcast time of at least one program may be extended from among a plurality of programs scheduled to be broadcast earlier than the broadcast disclosure time of the first specific program . the case where any one of the broadcast start time of the other second specific program of a particular program has been extended by a desired time in accordance with the extension of the broadcast time of the possibility of a certain program to be the prolonged A reservation recording control correction controller capable of preventing the reservation recording end time of the first specific program from being extended by a desired time shorter than a predetermined time when the reservation recording end time of one specific program is earlier than with Ru.

In the reservation recording control apparatus according to the present invention, at the start of broadcasting for a previously broadcasted program Even when recording a program that may be delayed, the recording reservation time is extended by the desired time. By lengthening, a desired program can be reserved and recorded until the end.

The broadcast-scheduled program memory 51 is connected to an external multiple broadcast wave decoder, and among the information included in the input program information It, at least the broadcast station Ibs, broadcast date Ibd, broadcast start time Ibb, broadcast end Information representing time Ibe and genre Ibj is accumulated.

  With reference to FIG. 2 and FIG. 3, program information It representing a program table when a television program is broadcast by character multiplex broadcasting will be described. In this example, the example is described with reference to a television program, but it goes without saying that the present invention is not limited to a reserved recording of a television program. As shown in FIG. 2, the program information It consists of individual codes representing various types of information. That is, the broadcast station information Ibs includes a broadcast station code Ca that identifies a broadcast station. The broadcast date information Ibd includes a broadcast start year code Cb that specifies the broadcast start year, a broadcast start month code Cc that specifies the broadcast start month, and a broadcast start date code Cd that specifies the broadcast start date. The broadcast start time information Ibb includes a broadcast start time code Ce that specifies a broadcast start time, a broadcast start minute code Cf that specifies a broadcast start minute, and a broadcast start second code Cg that specifies a broadcast start second. The broadcast end time information Ibe is composed of a broadcast end time code Ch that specifies the broadcast end time, a broadcast end minute code Ci that specifies the broadcast end portion, and a broadcast end second code Cj that specifies the broadcast end second. The genre information Ibj is a program genre code Ck that specifies the genre of the broadcast program. A packet of program information It consisting of these codes is broadcast while being superimposed on the vertical blanking period of the broadcast wave.

  Further, as shown in FIG. 3, the program genre code Ck representing the genre information Ibj is composed of a subcode Ck representing the contents of the genre. These subcodes Ck include, for example, a subcode Ck1 representing a movie, a subcode Ck2 representing a drama, a subcode Ck3 representing a sport, a subcode Ck4 representing a music, a subcode Ck5 representing an entertainment, and a subcode representing an animation Ck6, subcode Ck7 representing news, subcode Ck8 representing education, subcode Ck9 representing hobby, and subcode Ck10 representing other.

  Thus, in the present invention, the program information It, which is information for identifying a program, is stored in the broadcast scheduled program memory 51 in advance. Further, as described above, the program information It has been described by taking an example of the television program broadcast. However, the program information It is similarly configured for a data broadcast represented by computer data scheduled in the future.

  Returning to FIG. 1, the broadcast schedule program table generator 100 is connected to the broadcast schedule program memory 51, and based on the program information It stored in the broadcast schedule program memory 51, a predetermined time before and after the current time. Program guide information Ipt indicating the contents of a program scheduled to be broadcast over a range is generated.

  The display device 55 is connected to the broadcast schedule program guide generator 100 and displays the contents of the broadcast schedule program based on the program guide information Ipt. The user operates the operation input unit 56 to select the program to be recorded while viewing the program schedule scheduled to be broadcast displayed on the display device 55, and generates the recording reservation instruction signal Sc.

  The recording reservation program guide generator 200 is connected to the broadcast schedule program guide generator 100 to receive the program guide information Ipt, and is connected to the operation input device 56 to receive the recording reservation instruction signal Sc. Based on the recording reservation instruction signal Sc, the recording reservation program guide generator 200 generates recording reservation program guide information Ipts that specifies a program for which the user instructs recording reservation. The recording reservation program table information Ipts includes a broadcasting station Ibs, a broadcasting date Ibd, a broadcasting start time Ibb, a broadcasting end time Ibe, and a genre Ibj of a broadcasting program to be reserved for recording, and a recording reservation start time Srst. , Reservation recording end time Sret, and various recording reservation program parameters of program genre code Ck.

  The detector 54 is connected to the broadcast-scheduled program memory 51 and receives the program information It, and is connected to the recording reservation program guide generator 200 and receives the recording reservation broadcasting station Sbs and the reservation recording start time Srst. The detector 54 searches the program information It for the recording reservation broadcast station Sbs, the reserved recording start time Srst, and the genre code CkN (N is a positive integer) representing the content of the predetermined program, and starts broadcasting the program reserved for recording. Search for a program that may affect the time, that is, the reserved recording disturbing candidate program Sdp. For the sake of simplicity, hereinafter, the program reservation recording hindrance candidate program Sdp is abbreviated as a hindrance candidate program Sdp.

  Then, the detector 54 creates a disturbance candidate program table Sdpt representing the contents of the searched disturbance candidate program Sdp. That is, the detector 54 searches for the program information It recorded in the broadcast-scheduled program memory 51, the broadcast station information Ibs is the same as the recording reservation broadcast station Sbs, and the broadcast start time information Ibb is the reservation recording start time. All the programs Sdp that are earlier than Srst and whose program genre code Ck matches the predetermined program genre code CkN are found, and the interference candidate program table Sdpt is generated.

  As the predetermined program genre code CkN, a genre whose broadcast end time is often extended until the game ends, such as a sports broadcast, is selected. In this sense, the program genre code CkN can be defined as a reserved recording disturbing genre code CkN. In this sense, the reserved recording disturbing genre CkN may be set in advance to any genre other than sports broadcasts, or when the user operates the operation input device 56 to make a recording reservation, You may comprise so that it may input as a genre CkN.

  The recording reservation program guide generator 200 is further connected to the detector 54, receives the input of the interference candidate program guide Sdpt, and displays the recording reservation program guide information Ipts already generated and the interference candidate program guide Sdpt in comparison. A reservation-disturbing program guide TDp is generated. The display 55 is connected to the recording reservation program guide generator 200, displays the contents of the reservation-disturbance program guide TDp, and presents it to the user.

  The user looks at the reserved-interfering program table TDp displayed on the display 55 and determines whether or not to extend the reserved recording end time Sret of the program to be reserved for recording. When the user extends the determination result together with the determination result, the user inputs the extension time Tp to the recording reservation program table generator 200 (reservation recording control device TRC1) as the recording reservation instruction signal Sc using the operation input unit 56.

  Based on the recording reservation instruction signal Sc, the recording reservation program guide generator 200 rewrites the reservation recording end time Sret to a time extended by the extension time Tp, regenerates the recording reservation program guide information Ipts, and displays the display 55. And output to the recording reservation program memory 210.

  The scheduled recording program memory 210 is connected to the scheduled recording program table generator 200, receives and stores the regenerated scheduled recording program guide information Ipts.

  The display 55 presents the contents of the recording reservation program guide information Ipts to the user as a part of the above-mentioned reservation-interference program guide TDp. If the content of the presented recording reservation program guide information Ipts is satisfactory, the user operates the operation input device 56 to input the fact to the recording reservation program guide generator 200 as a recording reservation instruction signal Sc. On the other hand, if the contents of the recording reservation program guide information Ipts are unsatisfactory, the user determines and inputs the desired extension time Tp while checking the reservation-interference program guide TDp displayed on the display 55. That is, the user considers all the disturbing candidate programs Sdp displayed in the reserved-interfering program table TDp, and gives the recording reserved program table generator 200 the extended time Tp of the reserved recording end time Sret for all the reserved recording programs Srp. The recording reservation program guide information Ipts is generated by inputting.

  The recording device controller 220 is connected to the recording reservation program memory 210 and receives the recording reservation program guide information Ipts. The recording device controller 220 then, based on the input recording reservation program guide information Ipts, records recording broadcast station Sbs, reservation recording start time Srst, and reservation recording end time Sret specified in the recording reservation program guide information Ipts. Based on the above, a recording device control signal Scr for controlling the operation of the recording device 52 is generated. The recording device 52 is a recording / reproducing device such as a video tape recorder, for example, and records a broadcast program.

  As described above, when the user inputs a program to be reserved for recording using the operation input device 56, the reservation recording control device TRC1 may affect the end time (broadcast time) of the program reserved for recording accordingly. A high program is listed, and the user sets the recording end time of the recording device 52 by delaying it by a desired time.

  With reference to the flowchart shown in FIG. 4, the operation of the above-described reservation recording control apparatus TRC1 will be described.

  First, in step S <b> 2, the broadcast schedule program guide generator 100 creates program guide information Ipt representing the contents of the program scheduled to be broadcast based on the program information It stored in the broadcast schedule program memory 51. Based on the program guide information Ipt, the display 55 displays the program guide Pt scheduled to be broadcast as an image.

  In step S4, the user determines a program to be reserved for recording with reference to the program table Pt displayed on the display 55 in step S2. Then, the user operates the operation input device 56 to generate a recording reservation instruction signal Sc representing the content of the determined recording reservation, and outputs it to the reservation recording control device TRC1. The scheduled recording program table generator 200 of the scheduled recording control apparatus TRC1 sets the scheduled recording on the basis of the input recording reservation instruction signal Sc and generates the scheduled recording program guide information Ipts. In other words, the recording reservation program guide generator 200, based on the recording reservation instruction signal Sc, from the program guide information Ipt inputted from the broadcast scheduled program guide generator 100, broadcast station information Ibs (broadcast station code Ca) of the program to be reserved for recording. ), Broadcast date information Ibd (broadcast start year code Cb, broadcast start month code Cc, broadcast start date code Cd), broadcast start time information Ibb (broadcast start time code Ce, broadcast start minute code Cf, broadcast start second code Cg) The broadcast end time information Ibe (broadcast end time code Ch, broadcast end minute code Ci, broadcast end second code Cj) is extracted.

  In step S6, the scheduled recording program table generator 200 uses the detector 54 to broadcast on the same broadcast station as the scheduled recording program, that is, on the same channel, and to specify a specific schedule scheduled to be broadcast before the scheduled recording program broadcast time. Detects the presence of genre programs. That is, a program having the same broadcast station information Ibs as the recording reservation broadcast station Sbs of the program reserved for recording, the broadcast start time information Ibb before the reserved recording start time Srst, and the genre code CkN representing the contents of the predetermined program Is detected as the interference candidate program Sdp, the detector 54 searches the program information It stored in the broadcast scheduled program memory 51. As a code CkN representing a program of a specific genre, for example, a sub code Ck3 indicating sports is set.

  In step S8, when the interference candidate program Sdp is not detected as a result of the search in step S6, that is, a program having the corresponding broadcast station information Ibs, broadcast start time information Ibb, and program genre code CkN is not detected. In this case, it is determined as No. Then, the process proceeds to step S38.

  In step S38, the broadcast end time information Ibe is set to the reserved recording end time Sret, and the process ends.

  On the other hand, when the interference candidate program Sdp is detected in step S8, that is, the reserved recording start time of the program reserved for recording without ending at the end time specified in the broadcast end time information Ibe, such as sports (Ck3). If there is a program whose broadcast may be extended beyond Srst, the determination is YES and the process proceeds to step S10.

  In step S10, the detector 54 generates a disturbing candidate program table Sdpt representing the contents of all found disturbing candidate programs Sdp. Then, the scheduled recording program table generator 200 generates the reserved-disturbing program guide TDp based on the disturbing candidate program guide Sdpt and the program guide information Ipt. Further, the display 55 displays the reservation-disturbance program guide TDp.

  In step S12, the user looks at the reservation-disturbance program table TDp displayed on the display 55, and determines whether or not to decrement the reservation recording end time Sret of the reservation recording program. If the reserved recording end time Sret is not decremented, the process ends after proceeding to step S38 described above. On the other hand, when the reserved recording end time Sret is lowered, the process proceeds to step S14.

  In step S14, the recording reservation program guide generator 200 displays a predetermined reference extension time Tpp in the reservation-disturbance program guide TDp corresponding to each detected interference candidate program Sdp. Then, the process proceeds to the next step S16.

  In step S16, the user determines whether or not the reference extension time Tpp is appropriate as the extension time Tp for extending the reservation recording end time Sret of the recording reservation program Srp. If it is determined that the reference extension time Tpp is appropriate, the process proceeds to step S20.

  In step S20, the extension time initial value is set to the extension time Tp. Then, the process proceeds to step S36.

  On the other hand, if it is determined in step S16 that the reference extension time Tpp is not appropriate, the process proceeds to step S18.

  In step S <b> 18, the user inputs the extension time Tp using the operation input device 56. Then, the process proceeds to step S36.

  In step S36, the reserved recording end time Sret is rewritten to the time extended by the extended time Tp, and the recording reserved program guide information Ipts is regenerated and recorded in the recording reserved program memory 210.

  If NO is determined in step S8 and step S12, in step S38, the broadcast end time Ibe of the recording reservation program Srp is set to the reservation recording end time Sret, and the recording reservation program guide information Ipts is reproduced. And recorded in the recording reservation program memory 210.

  Thus, according to the reservation recording control apparatus TRC1 of the present invention, a program that is a program of the same broadcasting station (channel) as the program to be reserved for recording and is a program of a specific genre scheduled to be broadcast before the program to be reserved for recording. If there is a reserved recording disturbing program, the fact is presented to the user as a reserved recording disturbing program table, and the user is inquired about the necessity of delay in setting the recording end time of the program to be reserved for recording. Then, the user can determine the change of the recording end time in consideration of the presented reserved recording disturbing program guide, and execute the reserved recording so that the user can use it easily.

(Second embodiment)
A reservation recording control apparatus according to the second embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 5, the reservation recording control device TRC2 according to the present embodiment is arranged between the recording reservation program table generator 200 and the recording reservation program memory 210 of the reservation recording control device TRC1 shown in FIG. A management device 202 is added. The added recording reservation program manager 202 and the recording reservation program table generator 200 constitute a first recording reservation manager 200A.

  The recording reservation program manager 202, when the reservation recording end time Sret of the program to be reserved for recording by the user is extended by a desired extension time Tp, the reservation updated in step S18 or step S20 described with reference to FIG. The recording reservation program guide information Ipts is searched at the recording end time Sret, and a subsequent recording reservation program Srp that may be affected by the recording reservation time due to this recording extension is searched for as a recording reservation damage candidate program Svp. In this case, the recording reservation broadcast station Sbs is not a search condition.

  For the sake of simplicity, the recording reservation damage candidate program Svp is hereinafter abbreviated as a damage candidate program Svp. In addition, if the reserved recording end time Sret is extended, the reserved recording program Srp that may act as the disturbing candidate program Sdp for the subsequent damage candidate program Svp is referred to as the perpetuating candidate program Apc.

  The scheduled recording program manager 202 further generates a damage candidate program table Svpt representing all detected damage candidate programs Svp and outputs the damage candidate program table Svpt to the display unit 55.

  The user looks at the damage candidate list Svpt displayed on the display device 55 and determines whether or not to extend the reserved recording end time Sret of the program to be recorded. When the user extends the result together with the determination result, the operation input unit 56 is used to input the extension time Tp as the recording reservation instruction signal Sc to the recording reservation program guide generator 200 (reserved recording control device TRC2).

  When only one program is reserved for recording, the reserved recording end time Sret of the recording reserved program Srp is set to a predetermined extension time in order to avoid the influence of the preceding interfering candidate program Sdp as in the first embodiment described above. It is effective to extend by Tp. However, when a plurality of programs are reserved for recording, if one reservation recording end time Sret of the recording reservation program Srp is extended, the broadcast start time information Ibb of the subsequent recording reservation program Srp may be eroded. In particular, when the broadcast source of the two recording reservation programs Srp is different, the preceding recording reservation program Srp may continue to be recorded even when the broadcast start time Ibb of the subsequent recording reservation program Srp is reached. . In this case, the preceding recording reservation program Srp behaves as the disturbing candidate program Sdp with respect to the subsequent recording reservation program.

  Therefore, in this embodiment, the first recording reservation manager 200A causes one recording reservation program SrpO (O is a positive integer) to interfere with the subsequent recording reservation program SrpP (P is an integer larger than O). A case where the program can be a program Sdp is detected and an appropriate response is asked to the user. In response to the inquiry from the first recording reservation manager 200A, the user inputs a recording reservation instruction signal Sc that conveys his / her will to the first recording reservation manager 200A. The recording reservation program manager 202 generates recording reservation program guide information IptsR based on the user's will (Sc). The recording reservation program memory 210 records the recording reservation program guide information IptsR, and the recording device controller 220 generates a recording device control signal Scr based on the recording reservation program guide information IptsR.

  With reference to the flowchart shown in FIG. 6, the operation of the above-described reservation recording control apparatus TRC2 will be described. In the flowchart of FIG. 6, steps S22, S24, S26, and S34 are inserted between step S18 and step S36 of the flowchart shown in FIG. Therefore, the description of the operations already described with reference to FIG. 4 is omitted, and only the operations related to these newly inserted steps will be described.

  That is, after the processing from step S2 to step S16, the extension time Tp is appropriately set in step S18 or step S20, the process proceeds to step S22.

  In step S22, the recording reservation program manager 202 searches the recording reservation program guide information Ipts with the updated reservation recording end time Sret, and can be affected by the extension of the reservation recording end time Sret instructed in step S12. Search for potential damage candidate program Svp. Then, the process proceeds to the next step S24.

  In step S24, it is determined whether a damage candidate program Svp has been detected. If the damage candidate program Svp is not detected, it is determined No and the process proceeds to step S36. On the other hand, if the damage candidate program Svp is detected, it is determined Yes and the process proceeds to step S26.

  In step S26, the recording reservation program manager 202 generates a damage candidate program table Svpt representing all of the damage candidate programs Svp, and outputs and displays it on the display 55. Then, the process proceeds to step S34.

  In step S34, the user examines the influence of executing the reserved recording end time Sret extension in step S12 for each damage candidate program Svp displayed in the damage candidate program table Svpt. Then, the user determines whether or not to execute the extension process. When the extension in step S12 is executed, the process proceeds to step S36. On the other hand, when not extending, it progresses to step S38.

  As described above, in steps S22 and S24, the scheduled recording start time of the subsequent scheduled recording program Srp is the time (Sret) obtained by delaying the scheduled recording end time Sret of the damage candidate program Svp (SrpO) by the extension time Tp. By searching for Srst, it is detected whether or not there is a candidate recording program Svp in the recording reservation program Srp subsequent to the program delayed by the extended time Tp. The user sees the search result presented in step S26, and determines in step S34 whether or not to extend the reserved recording end time Sret of the damage candidate program Svp. Then, according to the determination result of the user, the reservation recording end time Sret is appropriately set in the above-described step S36 or step S38. Thus, in this embodiment, even if a damage candidate program Svp is found, the damage candidate program SvpO itself interferes with the subsequent recording reservation program Srp by simply extending the reservation recording end time Sret. The situation of becoming the candidate program Sdp can be avoided.

(Third embodiment)
A reservation recording control apparatus according to a third embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 7, the reservation recording control device TRC3 according to the present embodiment has a configuration in which the recording reservation program manager 202 of the reservation recording control device TRC2 shown in FIG. ing. The recordable time detector 204 and the recording reservation program guide generator 200 constitute a second recording reservation manager 200B.

  The recordable time detector 204 is connected to the recording device 52, detects the recordable time Trt remaining on the recording medium of the recording device 52, and generates the recording reservation capacity signal Sart. The recordable time detector 204 outputs the recording reservation capacity signal “Sart” to the display 55 to present the recordable time Trt of the recording device 52.

  The user looks at the recordable time displayed on the display unit 55 and determines whether or not to make a recording reservation and whether or not to extend the reserved recording end time Sret of the recording reserved program. Then, the user uses the operation input device 56 to input the determination result to the recording reservation program guide generator 200 as the recording reservation instruction signal Sc.

With reference to the flowchart shown in FIG. 8, the operation of the above-described reservation recording control apparatus TRC3 will be described. In the flowchart of FIG. 8, step S28 is added after step S22 of the flowchart shown in FIG. 6, and steps S24 and S26 are replaced with steps S30 and S32. Therefore, the operations already described with reference to FIG. 6 are omitted, and only operations related to these new steps will be described.
Similarly to the reservation recording control apparatus TRC2 according to the second embodiment, after searching for the damage candidate program Svp through the processing from step S2 to step S22, the process proceeds to step S28.

  In step S28, the recordable time detector 204 detects the recordable time Trt.

  In step S30, based on the recordable time Trt, the recordable time detector 204 is sufficient for the recordable time of the recording medium of the recording device 52 with respect to the extension time Tp set in step S18 and step S20. Judge whether there is. In the case of Yes, the process proceeds to step S36, and the reservation recording end time Sret is extended by the extension time Tp. On the other hand, in the case of No, the process proceeds to step S32.

  In step S32, the display 55 presents the damage candidate program Svp to the user together with the recordable time Trt of the recording medium of the recording device 52 based on the recording reservation capacity signal Sart input from the recordable time detector 204. Then, the process proceeds to step S34.

  As described above, the recordable time Trt of the recording device 52 is detected in step S28, and when the recordable time Trt is longer than the extension time Tp set in steps S18 and S20, in step S36 according to the user's intention. The reservation recording end time Sret is delayed by the extension time Tp. On the other hand, when the recordable time Trt is shorter than the extension time Tp, the fact is presented to the user in step S32, and the user's judgment is prompted in step S34. In this way, in this embodiment, a method for extending the recording reservation time can be selected according to the remaining capacity (recordable time) of the recording medium of the recording device 52.

(Fourth embodiment)
A reservation recording control apparatus according to a fourth embodiment of the present invention will be described with reference to FIGS.

  In the same manner as in the reservation recording control apparatus TRC1 according to the first embodiment, through the processing from step S2 to step S36, in step S40, the reference extension time updater 206 takes statistics of the extension time Tp.

  In step S42, the reference extension time updater 206 outputs the extension frequency Tp having the highest frequency in the statistics taken in step S40 to the recording reserved program table generator 200 as the reference extension time Tpp.

  In this way, statistics of the extension time Tp selected by the user are taken, and among the statistical data, an adaptive value is stored as the reference extension time Tpp, and is output to the scheduled recording program table generator 200. In step S14 at the next operation, the updated reference extension time Tpp is proposed to the user. The statistics may be taken for each genre, and an initial value may be set for each genre.

  In the above embodiment, as the time set by the user, not only the extension time Tp for delaying the reservation recording end time Sret but also the reservation recording end time Sret itself may be input. As described above, in this embodiment, the reference extension time Tpp is set using the statistical result of the past extension time, so that the trouble of the user's extension time setting operation is reduced, and the recording reservation program is displayed. Recording can be realized without being interrupted.

  As described above, the reservation recording control apparatus according to the present invention uses the stored program information to detect whether there is a program that is likely to be extended before the recording reservation program when recording reservation is made. To do. Based on the detection result, the scheduled recording end time can be set with a predetermined time delay from the broadcast end time. Therefore, it is possible to reduce the fact that the recording is cut off due to the extension of the previous program. In addition, since the user can be notified whether there is a program that is likely to be extended before the program to be reserved for recording, the user can be given an opportunity to determine whether to extend the recording reservation.

  Further, the user can set an optimal recording end time according to the content of the detected program.

  In addition, since the most frequently used extension time Tp set by the user in the past can be set as the reference extension time Tpp, the reservation recording control device can reduce the troublesomeness of the user setting the optimum recording end time. Can be realized.

The present invention relates to scheduled recording for receiving and recording a plurality of contents distributed by wire or wirelessly. It can be used for devices.
